On processing cycle query's strategy for semistructure data model and its role in design

There is no obvious schema information for the characteristic of self-describing semi-structure data, since the data structure is dynamic but not regular nor complete. The data mode often adopted is a directed graph with its root, in which it often appears a circular-like structure. In this paper we address the issue of querying semi-structure data. Particularly, we are interested in detecting circular-like structure, so that infinitude circulating can be avoided for the query on OEM model-based. As an application, the approach (the Processing Cycle Query's Strategy) proposed in this paper has been successfully implemented in the design of www. Ego365.com E-business network station (built by authors' team).
